Physical and chemical processes in the material science and in the wear-resistance corundum ceramics technology: nozzles for the underground soil-drilling bevelers

Abstract

From the perspectives of material science the analysis was carried out for the structural ceramic material's conditions and mechanisms of their abrasive destruction (wear) and
of their synthesis. The logistic flow diagram was formed for the physical and chemical processes and for the structural engineering in the high-abrasive technology which provides the serial transformations and conversions of the mineral raw materials into the tailored structural ceramic materials and products (nozzles and jets) with prescribed properties.
